FILE SIGNAL Filed April 27, 1939 In ventor Patented July 9, 1940 PATENT OFFICE FILE SIGNAL Coleman R. Ohamberlin, New York, N. Y. Application April 27, 1939, Serial No. 270,466

1 Claim.

Thepresent invention relates to new and useful improvements in file signals and has for one of its important objects to provide, in a manner as hereinafter set forth, an article of this character embodying a novel construction whereby the cardboard or paper will be frictionally gripped in a manner to securely attach the signal thereto.

Another very importantobject of the invention is to provide a signal of the aforementioned character which may be expeditiously applied to the cardboard or paper and removed therefrom.

Still another very important object of the invention is to provide a signal of the character described embodying stops of a novel construction engageable with the edge of the cardboard or paper for causing the signal to project therefrom.

Other objects'of the invention are to provide a signal of the character set forth which will be comparatively simple in construction, strong,

durable, highly efiicient andreliable in use, com

pact and which may be manufactured at low cost;

,All of the foregoing and still further objects and advantages of the invention will become ap-.

parent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding'parts throughout the several views, and wherein:

Figure 1 is an elevational view of an embodiment of the present invention, showing the article in use. 1

Figure 2 is a plan view thereof.

Figure 3 is a sectional View, taken substantially on the line 3-4 of Fig. 1.

Figure 4 is a view showing the signal before it is folded or bent upon itself.

Figure 5 is an elevational view of another form of the invention.

Referring now to the drawing in detail, it will be seen that the reference numeral 1 designates generally what may be referred to as' a substantially U-shaped clip which-is adapted to be mounted on a marginal portion of a cardboard or sheet, as at 2. The clip I comprises laminations 3 of suitable strips of material, such as Celluloid, which are adhesively secured together with a pair of spaced, parallel resilient Wires 5 therebetween.

The laminations 3 with the wires 4 therebetween are bent transversely upon themselves at an intermediate point in a manner to provide legs 5 which are adapted to frictionally grip the cardboard or sheet Z therebetween. The free.

ends of the'legs 5 are cut in diagonally opposite directions in the finished article, as at a, to

facilitate slipping the clip I on the cardboard or sheet 2. Struck inwardly from the longitudinal marginal portions of one of the legs 5 are tongues constituting stops l which are engageable with the edge of the cardboard or sheet 2! in a manner to cause the clip I to project therefrom. As shown the edgeof sheet 2 lies' between 5. As above stated, the stops 1 are adapted to engage the edge of the cardboard or sheet 2 for causing the clip l to project therefrom. The article may be colored as desired. While the wires 4 give to the clip l the necessary resiliency for gripping the cardboard or sheet, no metal is exposed as said wires are enclosed by the laminations 3. In the form of the invention shown in Fig. 5 of the drawing, the stops l are omitted, thus permitting the clip I to be slipped all the way onthe cardboard or sheet 2 into engagement with the edge thereof.

It is believed that the many'advantages of a signal constructed in accordance with the present invention will be readily understood and although preferred embodiments of the" article are as illustrated and described, it is to be understood that further modifications and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is: 1

A signal clip of the class described ccmprisin a body formed of a pair of Celluloid strips, one placed on the other, spaced parallel wiresplaced between the strips, said wires being of resilient material and entirely covered by the strips, said strips being adhesively connected together and posed and extending toward the free end or" the limb. v
